A recent Zogby poll of more than 1,000 adults found that 63 percent of people don't have a clear sense of what financial information is stored on their smartphones, and nearly 70 percent believe that storing payment information on their smartphone is unsafe (h/t Help Net Security).

Still, the survey, sponsored by PayPal and the National Cyber Security Alliance, found that one six respondents say they make at least 25 percent of all their purchases on their smartphone -- and more than half of respondents don't lock their mobile device with a PIN.

The survey also found that 53 percent of respondents were comfortable with the idea of replacing passwords with fingerprint identification, and 45 percent were comfortable with the idea of replacing passwords with retinal scans.


"The survey results clearly indicate that consumers are increasingly using their mobile devices to conduct transactions," National Cyber Security Alliance executive director Michael Kaiser said in a statement. "However, they also show that consumers need to get more active about mobile security, especially around basic security measures such as adding a PIN code or password to their devices and understanding what kinds of information their devices store."
